What is HVAC?

HVAC stands for heating, ventilation and air conditioning, and refers to the systems within your commercial building or residential home that heat and cool (condition) the space.

Why should I replace my AC and heating systems?

If your system is more than 10 years old, it is likely inefficient or at least in need of repair. Most new systems are up to 60 percent more efficient than those commonly installed a decade ago. Despite the upfront costs, it can be less expensive over time to install a new system than paying for ongoing maintenance and high monthly utility bills. With regular heating and cooling maintenance and service, you can expect a new HVAC system to last 15 years to 20 years.

What is involved in installing a new HVAC system?

In a new home, you may need to install ductwork, which is usually metal or fiberglass, insulation, refrigerant piping, electrical service and wiring, thermostats, registers and grills and more. Ductwork is important because it takes care of your home’s air supply and return. The supply ductwork attaches to the outflow and delivers air to each zone in your home. Return ductwork draws air out to be heated or cooled, and usually requires an air filter.

How do I choose the right size heating and cooling system?

When it comes to optimum comfort and energy efficiency, bigger is not necessarily better. An over-capacity heating and cooling system will not run as frequently or as long, which can result in poor control over your living space. Over- or under-capacity equipment is less energy efficient, and can result in higher monthly utility bills.

Hassler’s trained technicians and estimators make sure your new unit is properly sized for your home and your specific needs. We can do a home energy audit and give you a cost analysis that shows approximate operating costs and how much money you can save each month on energy costs.

What does an air handler do?

An air handler circulates conditioned air throughout your home. This makes it easier to filter and humidify or dehumidify air.

Why should I care about air quality and filtration?

Indoor air pollution can be 2-5 times higher than outdoor air pollution, according to the Environmental Protection Agency (EPA). Consider the amount of time you spend in your home, and the reasons to pay attention to air quality and proper filtration are clear. Unfortunately, some common household items (like furniture, fabrics and building materials) can emit potentially harmful gases or particles that can make you sick or unhealthy. This is especially a concern for anyone with asthma, allergies or mold sensitivity.

How can I increase the efficiency of my HVAC system?

There are a few simple things you can do to keep your system at peak performance.

  1. Regularly clean and replace your air filters with a quality product, or call us to check them.

  2. Keep the equipment operating at recommended levels, as specified by your Hassler technician.

  3. Use shades or drapes on windows to moderate temperatures in rooms that get lots of sunlight.

  4. Make sure your home has properly installed, adequate insulation.
